Application filed .June SO, 1926 Serial No.,119,669.

This invention relates; to' labor saving apparatus and moreparticularly to means for 'iacilitating the carriage and discharge ot: )l; stic material after= it .is taken from 3 i its mixer or othersource, to different points in theprepared form or chambers which are to be tilled. V v I 'i'iii; object is to provide awheeled, portable conveyor and pourerwhich is of a capacity to carry many times a s-much batch asmay be. carried in a: hand wheelbarrow so that the present invention will eliminate equipment and a crew o'fioperatives and will there: fore eii'ect an economy in labor, in equip-- ment and in time of portagelot material.

A not-her object is to obviate the usual practice ottipping ertilting a wheelbarrow to discharge the batch into a chute or a form,

and an object is to provide a valved, flexible I spoutwhich can be directed to places of fill. near or remote from the portable conveyor. In other words, an object is to dispense with costly metal and woodenpouring chutes. In this connection, an object is to provide a capacious hopper which can be detached from its wheeled carriage and carried by derrick and boom or by overhead cable to the work which is 'to be filled, and there dis-- chargedin an effective and ready manner not accomplishable by'other form of apparatus. An advantage of such a form of portable and hoistable hopper .is the elimination of a vast amount of false-work, platform runways and elevators. p

A, further object is to provide a safety or duplex valve means whereby in'case of jamming of one "shutter against a stone in the mix the other shutter will form a safety which may then be operated-to close the throat of the spout; an additional purpose being to provide a valve means which may be controlled from either side of the conveyer as maybe necessary in some vcases.

An object is toeprevide a set of hopper units and a carriage which may be operated as a shuttle carrying the units in a. rotation system between batch mixer and the fill.

Other objects and advantages will be made manifest in the ensuing specification otlan embodiment of the invention illustrated herewith; it'being' understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is here claimed.

Fi re 3v is crossesection ot the hopper. Figure .4: is a sectional detail of the spout The conveyer includes an elongated tank or hopper 2 whose walls and bottom converge toward a spout throat here shown, as in the cent-er o't' the hopper bottom; this being soshaped to have no angular corners and being designed to facilitate gravity discharge oi? the load. The rim of he hopper is rolledat 4t over stifiening bars Sconnected bycornerclbows 6. ,V

a I prefer that the hopper be provided with suitable means enabling; "attachment of appl icahle liftingor" hoistftacltleT so. that the hopper can be quicklyswu-ng to a desired location especially where access bywhcelbarrow is diflicult or impossible. Suchmeans is here shown as including strong saddle cable 7 secured to the hopper bottom by straps 8 one of which has horns 9. i Parts of the cable are passed up through the corners of the hopper and have eyes 7 Ior tackle T. The spout throat 3 is provided with a duplex valve device including an upper shutter 10 and a lower shutter 11 which have handles extending to opposite sides of the hopper to enable opening and closing oi? the throat from either side. Either or both of the shutters lIIQylIQVQ an extension chain or line 12 which can be pulled to open its shutter when the hopper is suspended in a position, as from a cable or boom, remote from the operator.

Below the valve means is a detachable I spout 15 consisting of one or more interchangeable sections of canvas hose so that its outlet may be disposed as desired along a form or chamber to be filled without he quent short movements of the conveyer.- The horns 9 provide convenient rests or hooks for the end of the spout when this is notin use.

An auxiliary shut-oil device 16 is provided at the outlet end of the spout 15 sothat it can be closed as may be desired by the operative at the fill when the throat shutters are out of reach, as when the hopper is swinging in air from a boom. It willbe seen that the long flexible spout is a'substitute torvarif,

ous forms of chutes. I

P r e pera es are at t e hutt r- 11 is opened as needed along the work to permit the batch to run off. In the event that a shutter ams on a piece of stone as the shutter is being closed then the second or normally open shutter is closed to effect a complete shut off of the throat.

The carriage for the hopper has a top frame on which the rim at of the hopper will rest. The frame has legs 21 at its sides and well in from the ends so that the front and rear wheels 2223, carrying the frame, will be inside the end lines of the hopper and thus permit close operation of the eonveyer around and up to obstacles. The legs 21, which are suitably braced, are of such height as to elevate the hopper and provide easy access by workmen to the shutters in the spout throat 3.

The conveyer may be pushed or pulled and steered cither by motor power or manually and is provided with a tongue 25 for such purpose.

What is claimed is:

1. A portable plastic batch conveyer and pourer including a rimmed batch hopper, a spout in its bottom, valve means controlling flow from the spout, and a carriage having a top, bearing frame on which the hopper rim is mounted.

2. A portable plastic batch conveyer and pourer including a batch hopper, a flexible discharge spout in its bottom and valve means controlling flow from the spout; said .hopper having brace horns for receiving the discharge end of the spout when this is out of use. 7

A plastic batch eonveyer and pourer including a wheeled carriage having an elevated top, bearing frame, and a portable hopper having a top rim removably nested on the frame; the hopper having a fiexiblepouring spout in its bottom and which is directable variously from the carriage to discharge a batch from the hopper.

4. A plastic batch conveyer and pourer including a wheeled carriage frame, and a portable hopper removably nested on the frame; the hopper having a flexible pouring spout in its bottom and which is directable 'ariously to discharge a batch from the hopper; the frame having a top resting structure and the hopper having a top rim nesting on said structure. 7
